So we find yet another damsel in distress. This Assassin can be found in the Southeast corner of the Bayezid District, right next to the far Assassin's Den, Healer, Blacksmith, and Bank .You'll have to liberate the district from the Templars first.

Kill the soldiers, follow her to her shop, and talk to her again to gain a level 5 Assassin. Recruiting is so easy to do when they owe you their life.
